project_key: JBEPP During run of performance test for anonymous user with 200 concurrent clients, I noticed this exception in server log at the startup of test: 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) java.lang.NullPointerException 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.application.ModelAdapter$1.getProducerOfferedPortletContext(ModelAdapter.java:130) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.application.UIPortlet.setState(UIPortlet.java:806) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.util.PortalDataMapper.toUIPortlet(PortalDataMapper.java:243) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.util.PortalDataMapper.buildUIContainer(PortalDataMapper.java:403) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.util.PortalDataMapper.toUIPortal(PortalDataMapper.java:360) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.workspace.UIPortalApplication.addWorkingWorkspace(UIPortalApplication.java:481) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at org.exoplatform.portal.webui.workspace.UIPortalApplication.<init>(UIPortalApplication.java:186) 2010-09-20 14:52:00,443 ERROR [STDERR] (http-perf11%2F10.16.88.189-8080-119) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) I am attaching server log, where can be seen that exception occured in 4 tomcat worker threads and then another exceptions can be periodically seen in server log for these threads. I tried more builds but I am not able to simulate it reliably. It's first time I saw this exception during performance build. I am not sure if this could occur also in EPP 5.0.0.GA. So looks like concurrency problem... Let me know if I should investigate more and provide more info about this issue.

Postponing, hard to reproduce, would appreciate more details and info if that still occurs
I did not see it in any performance test during EPP 5.1.0 ER2 testing. So it's possible that it is already fixed but I am not sure. At this moment, I don't have reliable way how to reproduce it. I will probably look at it later after EPP 5.1.0 ER2 testing.
Pls give it a shot with ER3.
Has this issue been resolved? Since it's from a performance test, does it need to be Release Noted? (ie: does it affect customers?)
Release Notes Docs Status: Added: Needs More Info
I did not see it in latest performance tests with EPP 5 ER3 and it's really only from performance test. I suggest to not cover it in release notes.
Thanks Marek.
Release Notes Docs Status: Removed: Needs More Info Added: Not Required
I remove the fix version and keep it alive just for future reference if needed
Release Notes Text: Added: Resolving, because we didn't see this issue for very long time during performance testing and seems that some related code was changed in the meantime.
